Absolutely the best fluid to keep your transmission shifting smoothly and no overheating. Towing a 6,000 lb trailer and shifts are solid, never any issues and trans temp stays under 225 degrees, even pulling hills in 100+ degrees. If you want the best, pay for the quality and avoid any issues.

I've used Amsoil products for some 20 years and used them in place of o.e.m products they are quite reliable and are easy to access.

Did a full fluid swap on my 2012 Silverado 1500 w/6L80e transmission when I bought the truck and it shifted great. Ran it for almost exactly 45,000mi and I do quite a bit of towing my boat with the truck. Might see 180-190°F trans temps on the hottest days of the year when not in the interstate. Just changed the fluid again and it’s shifting notably smoother than it was before the swamp. Can’t say if it is AMSOIL, regular fluid change intervals for it, and some transmission tuning by Black Bear performance but I’m the only person I know first hand that has a 155k+ mile 6L80e that hasn’t needed a rebuild.

This seems to be working good. This is the second year using AMSOIL (OE Fuel-Efficient 100% Synthetic Automatic Transmission Fluid) for a Ford EDGE. My Sport seems to shift faster, and smoother, but sometimes its shifts so fast, that it feel like a harder shift like a shift kit would give you. I down think this is bad, you just have to remember, ford has an adaptive shift learning stratagy to optimize performance, and paddle shifting can cause the Trans to act different, if you use it alot. Myself I try not touse it.

Used this in power steering and it is quiet and smooth.

Changed the transmission fluid in my 2017 Toyota Highlander at 60,000 miles definitely seems to be shifting smoother. Will definitely use it again at next change interval.

I put a thousands miles a week on my Elantra and have been running all amsoil products. At 130k miles I am not burning or consuming any oil.

Have ordered before. Product is good but this order hasn't shown up in 11 days and tracking shows no estimated delivery pending. Looks to be lost and will have to file claim.

I’ve used this transmission fluid in several high performance 4l80e transmissions and haven’t had any issues. Does well with heat and low temperatures. Would definitely buy again.

I put it in a 2021 Pacifica. It Quieted down the noisy shifts I was having after about a hundred miles. It was just a drain and fill.

Much smoother shifts since using AMSOIL OE Fuel-Efficient 100% Synthetic Automatic Transmission Fluid.

Rebuilt the transmission and went with syn. trans fluid as I wanted a very good quality fluid to use.

Ordering the kit just makes it easy to ensure you have everything you need. Been using AMSOIL for years, 250k on my LML still running strong.

I was skeptical at first because I've always used Honda OEM ATF. I've read reviews on Amsoil and 2 years later decided to give it a go. I should have used Amsoil 2 years ago as this product is amazing. My transmission not only shifts smoothly and effortlessly. I now feel more confident driving than with Honda OEM ATF. I had a harsh shift from 3rd to 4th gear and Amsoil ATF fixed that problem. Just a few dollars more than Honda ATF is well worth it the money.

The best oil first time using for transmission I'll be using only for engine definitely is the best for everything loyal customer Thank you Amsoil

I recently replaced my transmission fluid in my '15 Ford Escape w/synthetic Ams fluid. A real difference! Smooth shifts and gained 2 mpg on hwy. Highly recommend.

Amsoil the best oil out there

We use this instead of Toyota WS fluid, some transmissions have over 250000 miles

Put this in a jeep for a friend, fixed shuttering when cold and stiffening up shifts, friend really appreciated it and recommends to anyone that has a beater with a bit of transmission problems. Just make sure you flush all old fluid out of torque converter and cooler lines, and replace filter
